pcre - Apache installation; libpcre error

Question

When installing Apache on Ubuntu 11.10, I get the following error:

configure: error: APR not found. Please read the documentation.

I followed the instructions here, then, I get the error below:

configure: error: pcre-config for libpcre not found. PCRE is required and available from http://pcre.org/

What am I doing wrong and how can I resolve it?

Answer 1

1. Download PCRE from PCRE.org

2. Compile it with a prefix and install it:

./configure --prefix=/usr/local/pcre
make
make install

3. Go back to where your Apache installation is and compile Apache with PCRE:

--with-pcre=/usr/local/pcre
